Fast geolocation solution for bistatic interferometric synthetic aperture radar configuration of inclined geosynchronous transmitter with low earth orbit receivers

Abstract: Spaceborne interferometric synthetic aperture radar (InSAR) technology is an effective method to obtain digital elevation model (DEM) data. The bistatic InSAR configuration of the inclined-geosynchronous (InGEO) transmitter with low earth orbit (LEO) receivers (InGEO-LEO) is a novel InSAR system to acquire terrain information. This novel system is characterised with high resolution, wide swath and timeliness, but the Newton iterative method is time-consuming to solve the bistatic InSAR equations for fast DEM g… Show more

“…Various processing algorithms have been developed to deal with challenges like high squint angles [5] and time-varying parameters [6]. Accurate range models [7] and motion compensation techniques [8][9][10] are also critical for focusing. Moreover, some works focus on performance optimization and parameter calculation for satellites in elliptical orbits [11].…”
